support arm64 architecture

[longquan7]

I want to build this image to support arm64 architecture,but I don't find arm64 package at this http://repo.mongodb.org/apt/debian/dists/jessie/mongodb-org/3.5/Release , So I want to konw this image whether or not support arm64 architecture.

[ehershey]

There are no MongoDB Debian Arm releases. You can install Ubuntu packages from http://repo.mongodb.org/apt/ubuntu/dists/xenial/mongodb-org/3.5/Release

@tianon - are there suitable alternatives available to put together a multiarch MongoDB Docker image based on Xenial?

[tianon]

@ehershey so would it be fair to say that upstream supports/recommends Ubuntu (specifically Xenial) over Debian? If so, it probably makes sense to simply switch the default base of this image on that basis alone, and then arm64 becomes a side benefit of following upstream's official recommendations more closely. 😇

[tianon]

Size difference for 3.5 on the current Debian Jessie vs Ubuntu Xenial is ~43MB increase (~371MB up to ~414MB). A tiny bit painful, but worth it IMO if the result is closer to upstream's official recommendation / willingness to officially support.

Edit: that's even cheating a little bit, since I updated gosu to 1.10 at the same time, which shrank that layer from ~3.79MB down to ~1.64MB. 😇

[tianon]

Just for reference, here's the 3.4 Dockerfile I built based on Xenial:

@tianon @ehershey it looks like a switch to a xenial base image may have even more plausible multiarch images in the future, based on testing http://repo.mongodb.org/apt/ubuntu/dists/xenial/mongodb-org/testing/multiverse/ having 5 arches (amd64, i386, arm64, ppc64el, s390x).

[tianon]

I wonder how many folks we'd break by switching to Xenial -- probably less here than over in MariaDB. 😄

[Ognian]

@tianon just tested your docker file from this thread as it is (mongodb 3.4) and edited for mongodb 3.6 on a raspberry pi with 64 bit suse leap 42.3 --> it just works :-) (which is great)
I think you should somehow make it available either in exchange of this repo or if you worry about compatibility even under a different name...

[poupryc]

Can official integration be considered?

[rpascal]

@Ognian would you be able to share your code with me? I am having a lot of trouble running on a raspberry pi it never finish, always crashes on something. Thank you.

[Ognian]

@rpascal there is nothing special, I'm using exactly @tianon 's Dockerfile posted 5 messages above this one and the docker-entrypoint.sh from this repo;
Meantime I've even switched to mongodb 3.6
the changes therefore are:

ENV GPG_KEYS \
# pub   4096R/91FA4AD5 2016-12-14 [expires: 2018-12-14]
#       Key fingerprint = 2930 ADAE 8CAF 5059 EE73  BB4B 5871 2A22 91FA 4AD5

# https://docs.mongodb.com/manual/tutorial/verify-mongodb-packages/#download-then-import-the-key-file

and

ENV MONGO_MAJOR 3.6
ENV MONGO_VERSION 3.6.0

The most troubles I had, was to to get the base os stable, I'm using now the latest fedora rawhide, but fedora 27 and SUSE leap 42.3 (all 64bit) worked also...
